The Drum Mark Sensor looks at the drum mark (~13mm x~13mm square on the drum) to determine the condition of the drum. The Image Density Sensor looks at a black patch of toner written onto the drum by the laser. The ID sensor can give low readings if the drum is too worn or light shocked, if the ID sensor is bad, dirty or unplugged, or if the black patch is poorly developed. You covered the first two choices. Now look at the condition of the developer. You can run sim 25-01 to see what the toner sensor reads without changing any settings), or you might have a worn out mag roller or some sort of an agitation problem (such as no drive: you can also test that in sim 25-01). If I remember correctly good developer typically stirrs at about 85-105. I hope this helps.
